D shackles have multi-purpose use and are attached through key pin, clevis pin or captive pin - ideal for halyards and for other line and wire connections. Similar to the standard D shackles, the Wide-D Shackles have a wider internal width clearance for fitting to wider, irregular shaped or multiple objects. Although the Wide-D type typically has a lower breaking load than a traditional shackle, it comes in handy when fitting to those places where a standard shackle will not work.
